comparing objects from a binary file

[zifeer]

I have created a binary file with 30 locations (from 0 -> 29). It's supposed to store objects of this class:

class employee {
private:
	char name[25],telephone[15];
	int room;
public:
	employee(char []="",char []="",int=0);
	char *getname() { return name; }
	char *gettelephone() { return telephone; }
	int getroom() { return room; }
	employee &setname(char n[]) { 
		strcpy(name,n);
		return *this;
	}
	employee &settelephone(char t[]) {
		strcpy(telephone,t);
		return *this;
	}
	employee &setroom(int r) {
		room=r;
		return *this;
	}
};

employee::employee(char n[],char t[],int r) {
	strcpy(name,n);
	strcpy(telephone,t);
	room=r;
}

Now, inside main I have this function being called:

void addEmployee(employee &em,fstream &df) {
	employee em2;
	int soem=sizeof(em);
	char name[25],telephone[15];
	int room;
	cout<<"Enter the name of the employee.\n";
	cin>>name;
	cout<<"Enter the room of the employee.\n";
	cin>>room;
	cout<<"Enter the telephone number of the employee.\n";
	cin>>telephone;
	em.setname(name).setroom(room).settelephone(telephone);
	bool wrote=false;
	if (findEmployee(em,df) == -1) {
		for (int i=0;i<30;i++) {
			df.seekg(i*soem);
			df.read(reinterpret_cast<char *>(&em2),soem);
			if (em2.getroom()==0) {
				wrote=true;
				df.seekp(i*soem);
				df.write(reinterpret_cast<const char *>(&em),soem);
				break;
			}
		}
		if (wrote)
			cout<<"Succesfully added employee to database.\n\n";
		else cout<<"Database is full.\n\n";
	} else
		cout<<"An Employee with those information already exists.\n\n";
}

and this is the findEmployee function:

int findEmployee(employee &em,fstream &df) {
	int index=-1;
	employee em2;
	for (int i=0;i<30;i++) {
		df.seekg(i*sizeof(em2));
		df.read(reinterpret_cast<char *>(&em2),sizeof(em2));
		if (strcmp(em2.getname(),em.getname()) == 0 && 
strcmp(em2.gettelephone(),em.gettelephone()) == 0
			&& em.getroom() == em2.getroom()) {
			index=i;
			break;
		}
	}
	return index;
}

It seems to always say that the employee does not exist, even though I am entering the same data everytime. How can I compare objects froma binary file?
